# Regression test LLM apps and agents with metrics, traces, and eval suites using DeepEval

Run repeatable eval suites against prompts, RAG pipelines, and agents so regressions surface before release.

## Prerequisites

Python or Node.js, API access to an LLM judge or compatible local models, CI optional

## Installation

Use the upstream install or setup path that matches your environment:
- pip install -U deepeval

Requirements and caveats from upstream:
- Deepeval works with **Python>=3.9+**.
- python
